Hi Jean !
Good advice from Ralph - it does work best to run the wiring up
inside the wing strut, along with the tubing for the pitot. By all means,
install a pipe to carry the wires - whether metal or flexible plastic
is your choice...
For some reason, Mr. Murphy does not like the idea of wiring
running up inside the leading edge ! The nose section of the wing
forms a "D" tube, which is a large part of the strength of the wing -
maybe he felt the holes in the nose ribs would weaken it - I don't
know.... But - it might be best to run the tube for the wires
BEHIND the middle spar. There's certainly lots of room to work
there !
You could run the actual wires now, or just run a piece of
heavy twine or rope to pull wires through later. It's a good idea
to leave a rope there anyway, in case you want to add or
replace wires later. As Ralph said, put in all the wires you might
need - if you use the Fife wing tips, you will need wires for the
landing lights that are in the tips, as well as the nav & strobe lights.
I would suggest the 3 light Aeroflash combination strobe
& nav lights, with the white light at the rear, so you'll be legal for
night without an extra light on the tail (although a tail light
& strobe is not a bad idea !). The Aeroflash unit looks cleaner
than the Whelan, and costs considerably less. It also has
the power-packs in the wing tip, instead of in the fuselage
like the Whelan. With the pack in the fuse, you are running
very high voltage all the way out to the tip - this can add a
LOT of radio noise !! The only down side is that the Aeroflash
may not be quite as bright as the Whelan ..
Keep rivetting - IT'S WORTH IT !!! :-)

Hello everybody
The work on my wing is very but very fun! A question:
In the manual, they do not talk about the wiring... Should I have do some
now before close the wing or evrything can be do after? Should I install
some tubing across the nose rib and how?
